I have no idea what the bearing was set at, as noted in my remarks. To me it sounded like a traditional board that was somewhat lacking in bearing. I don't know whether or not it is lacking in bearing for that design since I lack so many particulars. But it's fair to ask the question even if I don't know the answer. I am hearing something, what are the cause(s)?

It all comes down to stiffness and mass, however it's arrived at. Ron N
